    <p>Looking at your applicationContext.xml again, I noticed you're not assigning an entityManager with your transactionManager declaration. I'm not sure if Spring will implicitly set it, but if it doesn't it would explain why your persists are not working. </p> <p>For example, change:</p> <pre><code>&lt;bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" /&gt; to &lt;bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"&gt; &lt;property name="entityManagerFactory" ref="entityManagerFactory" /&gt; &lt;/bean&gt; </code></pre> <p><strong>UPDATE</strong></p> <p>I've only configured Spring+JPA with Container-managed Entity (looks like your intention as well) - never really Application-managed. From what I know, in Container-managed with Spring, you don't really need to configure a Persistent Unit. I'm not 100% sure if this will help but try changing how your entityManagerFactory is declared in applicationContext.xml.</p> <pre><code>&lt;bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"&gt; &lt;property name="dataSource" ref="dataSource" /&gt; &lt;property name="packagesToScan" value="com.app.payment" /&gt; &lt;property name="persistenceProvider"&gt; &lt;bean class="org.hibernate.ejb.HibernatePersistence" /&gt; &lt;/property&gt; &lt;property name="jpaProperties"&gt; &lt;props&gt; &lt;prop key="hibernate.dialect"&gt;org.hibernate.dialect.MySQL5Dialect&lt;/prop&gt; &lt;prop key="hiberate.show_sql"&gt;true&lt;/prop&gt; ... //additional props &lt;/props&gt; &lt;/property&gt; &lt;/bean&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
